This is what I want. However, I could not understand what was going on...
I have a DataTable. It has many columns and rows. I wish to sort out only those rows that meet a certain criteria.
In this case, this datatable contains, for simplicity, just two columns
1 Incoming Mail
2 Incoming Mail
10 Outgoing Mail
11 Outgoing Mail
I wish to, somehow, filter out "Outgoing Mail" and keep "Incoming Mail".
